Rainbow City

If he says he doesn’t want to go when he has to go, Kwak Soohwan will be in danger. Seokhwa clenched his mouth shut tightly. A shudder, and his inner member expanded once more. Seokhwa twisted his body to break free, but an immense force deprived him of his freedom. He had always disliked being controlled by others through force. Although Kwak Soohwan had never forced him, Seokhwa suddenly felt anxious due to the extreme difference in strength.

He forcefully grabbed both of Seokhwa’s arms.

“Major…!” Seokhwa called out softly.

“Uh!”

His vision turned white for a moment before the dreary wall came into view. His member, pushed in as far as it could go, pressed against his buttocks. The shock of it being pulled back forcefully and then thrust inward caused a surge of nausea. Although he gripped the bandaged arms underneath, it felt like his wounds were reopening due to the pressure.

As Kwak Soohwan relentlessly pounded inside with tremendous force, Seokhwa’s prostate began to swell. With each thrust of his member, Seokhwa let out sobs from his contorted mouth. With pleasure and pain intermingling, his mind grew hazy.

“Is it that easy?”

Kwak Soohwan forcefully plunged his member to the hilt as Seokhwa’s widened mouth failed to swallow the saliva that dripped onto the floor.

“Am I nothing to Dr. Seok?”

“Uh!”

His nape was bitten hard. He repeatedly thrust inside deeply, causing a pounding sensation. He couldn’t close his mouth. Yet, despite his movements, Seokhwa’s member remained erect, swaying with each motion. Not only did he thrust upward, but he also vigorously brushed against the sides, causing a rush of fluid with each stroke.

Kwak Soohwan roughly manipulated his member with his hand.

“I’m here exposing myself like this, damn it. How will you manage without me? Is there anyone who can take care of you as well as I do?”

“…I don’t want this. I hate this.”

Seokhwa’s face twisted in agony for some reason.

He felt his body tremble uncontrollably, feeling the inner walls gripping his member tightly. Finally, Kwak Soohwan seemed to pour cold water on him. The marks on his white and smooth back became clear, and blood began to seep through the bandages wrapped around his arms.

When he forcefully withdrew his member, Seokhwa’s body sank to the floor. Seokhwa continued to tremble on the cold, wet floor. Kwak Soohwan didn’t know what to do and was on the verge of self-loathing.

This wasn’t what he wanted. It was just that Seokhwa seemed too eager to let him go…

Kwak Soohwan picked up the discarded uniform coat and wrapped it around Seokhwa’s body. His face, looking up, was a mess.

Seokhwa, not knowing why he was angry, just looked at him with confusion. Kwak Soohwan looked deeply upset, like a child who had been wronged so much that he couldn’t even scold. Seokhwa reached out and touched his forehead with his fingertips. He tried to pull away his hand, feeling the touch painfully, and quietly said,

“Are you cold?”

Kwak Soohwan lifted Seokhwa up. He walked outside and removed the plastic covering the mat, placing Seokhwa on it. He put on his pants and lit the fire in the portable heater placed nearby. Then, without looking back, he tried to go outside. Seokhwa quickly reached out and held onto Kwak Soohwan.

“Don’t go.”

“I’ll be outside. Dr. Seok, it’s better this way.”

“Together…”

Seokhwa grabbed him again with a weakened voice.

“Why, because it’s the last time, should I give you a proper pounding?”

Kwak Soohwan was on the verge of pulling out his tongue after spitting out these words.

“Let’s cool off your head a bit.”

Seokhwa tightly grasped his wrist.

He could have easily pushed him away, but Kwak Soohwan remained quiet like a defeated beast. When Seokhwa pulled him towards him, he was dragged to the mat and sat down. The oil heater, which initially smelled pungent, soon began to warm up the surroundings.

“Why did you do that?”

With black eyes, as if genuinely unaware of the reason, Kwak Soohwan found it difficult to speak honestly about why he had done what he did. If Seokhwa found out, how much of a fool would he think he was? He felt so pathetic, exploding with anger as if Seokhwa didn’t care about him at all.

He wasn’t angry right now, but he had definitely been angry before.

“Tell me. Or else I won’t know.”

Excessive honesty sometimes caused disturbances, but it also resolved issues that could otherwise linger. That’s why Kwak Soohwan liked the honest Seokhwa. In a world where schemes and tricks were rampant, Seokhwa stood out as pure.

“It seems that Dr. Seok likes stones more than me.”

Nevertheless, Seokhwa couldn’t be as honest as Seokhwa. The warmth of Kwak Soohwan’s cheek shimmered with the red heat from the heater.

“I like Major Kwak too. He’s always there to rescue me, even in dangerous situations.”

While others said all sorts of things, Kwak Soohwan was the only one who gave him a stone as a gift and accompanied him when he was always alone.

“That’s called the ‘suspension bridge effect.'”

“Suspension Bridge?”

“It means mistaking this excitement in dangerous situations as love.”

Kwak Soohwan tapped around Seokhwa’s heart. Due to the wind catching his nipples, he had to pull away hurriedly.

“I’ve never said it’s love.”

“So Dr. Seok wants to live and die with the beloved stone.”

As Kwak Soohwan’s words sharply pierced, there was nothing to be done about its childishness. Seokhwa briefly shrank from the rising tremor below, then grabbed his hand again. Although he didn’t understand why he had to compare himself with a stone, he wanted to convey this message.

“More stones are better, but Major Kwak is one. Stones can be replaced by other stones, but not Major Kwak.”

The words that came from Seokhwa were not idle chatter.

Kwak Soohwan trusted Seokhwa entirely, no matter what he said. Just like the old lady said. Haven’t you been saved too? It truly felt like salvation, and he couldn’t think of any other salvation.

“Is that so? Am I the only one in the world?”

Kwak Soohwan, quickly turning confident, brought his body closer. Seokhwa blinked his eyes as if he thought it was a given.

“There’s only one, but wouldn’t it be a waste not to look?”

“… “

As the strength in Kwak Soohwan’s backhand increased, Seokhwa, hesitating to answer, flinched. Perhaps he became cautious due to the memories from earlier. Still, Kwak Soohwan firmly reaffirmed the uniform wrapped around Seokhwa’s shoulders.

“Don’t let go if it bothers you.”

“I don’t want to be a burden.”

That damn “I don’t want to” phrase.

Kwak Soohwan firmly laid Seokhwa on the mat.

“Dr. Seok doesn’t even reach the level of a burden to me.”

As if to make up for his previous mistake, Kwak Soohwan gently kissed Seokhwa’s forehead. Even the eyelashes brushing against his face intensified his suspicions.

“I’ll be gentle. Make you feel good.”

Kwak Soohwan muttered as if talking to someone else, and kissed cautiously. As he twirled his tongue inside the warm mouth, Seokhwa tried to follow suit somehow. With one hand, he wrapped around Seokhwa’s member and continued to soothe the cheeks and ceiling with his mouth.

Gradually, he descended his lips to the nipple. He sucked on it, rolling the small nub with the tip of his tongue. It was time to suck on Seokhwa’s member while wiping his belly button and ribs with his tongue. Seokhwa raised both thighs as if to release tension. Kwak Soohwan’s lower body immediately surged with blood at the sight. He tapped the two firm balls together, where semen gathered as if it were about to burst.

“I want you to put it in…”

The hole that had been tormented quivered as it moved. Seokhwa brought his hand there and, as if trying to relax, directly touched the perineum as if massaging it.

“Seokhwa, Seokhwa hyung. If you do that somewhere else, it’s really not allowed.”

Seokhwa wrinkled his forehead in annoyance.

“I only want to be with Major Kwak.”

While saying this, he pulled down Kwak Soohwan’s pants with his other hand. Now, just Seokhwa’s words or actions alone might make him ejaculate. Kwak Soohwan closed his mouth straight and inserted his firm member deeply.

“Ha-ah!”

As Seokhwa took in Kwak Soohwan’s cock deeper, he exhaled sharply.

With a firm grip, Kwak Soohwan pressed down on Seokhwa’s lower abdomen, causing his thighs to tremble.

As the pressure both inside and out pressed against the prostate, Seokhwa didn’t know how to handle the pleasure. From Seokhwa’s erect member, thin drops of pre-cum dribbled down. Kwak Soohwan pressed on the abdomen a bit more with his palm and moved his hips slowly.

“Ah… Feels good… So… good…”

Seokhwa, with blurry eyes, let out a sigh. The pressure surrounding his member was immense, making him wonder if he was truly feeling it.

“Can I come once?”

He whispered as he nibbled on Seokhwa’s earlobe. Even though Seokhwa didn’t fully understand the meaning, he nodded his head several times. While the lower half was still rough, it was different from the unilateral pressure from earlier.

Lifting his knees, Kwak Soohwan hung Seokhwa’s legs over his shoulders. As he swiftly thrust his hips from below, Seokhwa scratched the mat. Kwak Soohwan rested his hand on Seokhwa’s back and pressed his body firmly against his. Without slowing down the insertion speed, he tormented the insides.

The mucous membrane softened, but still clung to the cock like a vice, and the stretched opening remained gaping. Uncontrollable moans burst out from Seokhwa beneath. Kwak Soohwan kissed Seokhwa’s parted lips.

Even with unfocused eyes, Seokhwa extended his tongue, surrendering to him entirely. With an unstoppable force, he thrust his entire body in with a loud thud. Inside, where nothing had touched before, the violent semen began to pour out. The pillar, which ejaculated while trembling, echoed inside the abdomen. It seemed to swell continuously with the constant ejaculation. Despite the cool body temperature, the interior felt like it was burning.

“…I’m full… Ah, it’s bursting…”

Although ejaculation hadn’t finished yet, Kwak Soohwan tried to withdraw his cock. Kwak Soohwan hugged Seokhwa tightly to prevent him from escaping and moved his hips slowly.

The cum, which tried to flow out, was blocked by his cock. He wanted to pull out and let the cun pour out fully. On the contrary, the heat filling his entire body with Kwak Soohwan was addictive.

“Ah, since Dr. Seok is receiving my semen for the first time, I have to take responsibility until the end.”

To take responsibility, Seokhwa heard the word for the first time. However, the sense of responsibility, although heavy, resonated with a good feeling. Even amidst the pleasure, Kwak Soohwan’s gaze was clear.

***

Seokhwa’s belly was entangled with sticky semen and thin fluid. Although Kwak Soohwan’s cock inside was still intimidating, the slippery walls accepted it effortlessly. Instead, he was relentlessly rubbing his semen-covered cock all over the insides.

Seokhwa, who might faint at any moment, followed diligently despite groaning.

“Are you okay?”

With each sway of the cock, the ejaculate that flowed out was accumulated on the uniform. Kwak Soohwan thought he was stubbornly persistent. But it wasn’t his fault that Seokhwa had made a sexual inhibitor that didn’t suit him.

“Uh-huh. I’m fine.”

Seokhwa grabbed the softening member that ejaculated several times. As he shook it, the erection started again. But it didn’t get as hard as before.

“…Major.”

“Yeah.”

Kwak Soohwan’s forehead was now sweating.

“I’m envious.”

After releasing his grip on Seokhwa’s cock, he lifted his testicles. Then, with half of it still exposed, Seokhwa stroked Kwak Soohwan’s shaft with his hand. With his glans twitching inside the slippery walls and his outside being touched by Seokhwa’s hand, his already hot body heated up even more.

“What, envious of what?”

“It seems good because it’s big.”

“What?”

“Because it’s big, it fills up inside, and the prostate keeps… being stimulated, ah, all the moisture inside is taken away. Too much ejaculation.”

Kwak Soohwan covered Seokhwa’s mouth with his hand. As he laughed, making the insides tremble, Seokhwa curled up and trembled.

“You can be honest when it’s like this.” It was absurd, but it felt good. Kwak Soohwan lowered his lips to Seokhwa’s arm, which was covered in sweat, and then firmly pulled his legs. Since the springs were obstructing movement, Kwak Soohwan, who was standing outside the mat, grabbed Seokhwa’s waist. He leaned his body down, bearing his weight.

Seokhwa looked up with eyes devoid of energy, not knowing what was happening. Suddenly, he forcefully withdrew his cock. Despite the tremendous sense of loss, his walls and hole convulsed, but what came rushing in was even faster. It made a squelching sound. He repeatedly pulled out completely and then pushed back in. Each time he withdrew, the thick glans scraped out the remaining semen, dripping down along Seokhwa’s buttocks.

“Ah, ah!”

Seokhwa only moaned helplessly, unable to form words.

While roughly probing inside, Kwak Soohwan glanced down at the inserted area. Each time he pulled out, he urged the gaping hole to come in faster, and as soon as it came back in, he thrust back in forcefully. After pulling out firmly, he pushed it back in deeply, stirring up the soaked interior.

Seokhwa tensed up and squirmed his legs. “Major, I can’t take it anymore.” But the words didn’t come out. Once again, the sensation of ejaculation hit hard against the back of his head on the mat, but Kwak Soohwan continued irregularly, violating below. Suddenly, semen erupted from Seokhwa, but it was excessively thin.

No, stop. Stop moving. His tongue stiffened, and only sobs escaped. With each thrust of his hips, fluid leaked from his member. Seokhwa felt like his pupils were rolling back, so he bit down hard on his lips. The sensation of the hole being turned inside out and then pushed back in now felt almost terrifying.

Feeling like he couldn’t hold on any longer, Seokhwa tried to push Kwak Soohwan’s chest away. But as he pushed his lips together, Kwak Soohwan folded Seokhwa’s body in half, pressing it down. He didn’t stop his hips, and Seokhwa, completely messed up, was even soaked in tears.

When Kwak Soohwan felt his thighs stiffen even more, he began ejaculating inside again. The unreceived walls redirected the ejaculate through the crevice. Kwak Soohwan, feeling like he couldn’t go on, ejaculated while still inside, firmly grasping his cock. With a gurgling sound, semen poured out, and the ejaculate that splattered from the cock scattered onto Seokhwa’s face. Seokhwa’s body, reaching its limit, collapsed limp. Kwak Soohwan reached out in surprise, but thankfully, he was still breathing.

He still half-pressed down on the still-standing cock as if to regain his senses. He pulled out the soaked uniform from under Seokhwa’s body without effort. He reduced the heat from the heater and took out toiletries and towels from one of the boxes. Was it too intense? He wet the towel and began wiping Seokhwa meticulously from his face. The unpleasant feeling of wiping a corpse on a whitened face crept over him.

As he gently massaged his chest, he felt the traces of a beating heart and the fluctuating breath. He wiped his entire body to remove any stickiness and then placed a towel under his buttocks.

Kwak Soohwan filled a pot with cold water and placed it on the heater before starting his shower. As he looked towards where Seokhwa, the Federal agent, was, Seokhwa began to toss and turn slowly. Since he didn’t have spare clothes, he only wore pants and a shirt. He hurriedly approached Seokhwa’s body and comforted him. Wanting to hug him tighter, he felt an urge.

“What if Dr. Seok gets pregnant?”

At the mumble, Kwak Soohwan quickly lowered his head. Seokhwa was staring with narrowed eyes.

“You know it’s a joke, right?”

With a slight smile, he patted Seokhwa’s head once while still providing support. Seokhwa had no strength to speak and simply placed his hand on his chest. Inside his belly still bubbled with heat.

***

Hmm, yeah. The man walking down the stairs was singing loudly. He seemed to be in high spirits and had a lively look in his previously dull eyes.

Choi Hoeon descended into the basement of the mansion and turned on the incandescent bulb. A man in casual clothes was sitting there, with his hands and feet tied, blood dripping from his nose.

“How does a sparrow catch a white tiger?”

The man’s eyes widened as soon as he saw Choi Hoeon.

“Your nose keeps bleeding.”

Choi Hoeon sat down in front of him, looking at him with a pitying expression. Around him, stainless steel surgical tables and scalpels were on the right, while cabinets filled with medication were on the left.

Choi Hoeon reached out and removed the man’s gag. Whether he was a soldier assessing the situation or not, he didn’t shout or beg for his life. Being an A-rank tracker, he must have received some level of education.

Attempting to achieve something publicly by acting on his own, he was lucky enough to have been discovered by Kwak Soohwan, who had left a woman at a payphone. Although she followed him because she knew the direction Kwak Soohwan had moved in, the destination they arrived at was a strange forest. It wasn’t luck, but misfortune.

“Who are… you?”

The tracker didn’t have information about Choi Hoeon, a Yeouido Shelter researcher.

“You must have been instructed not to take personal action, right? Why didn’t you listen and bring misfortune upon yourself?”

Choi Hoeon sat down with a regretful expression, pulling a chair closer. Around him, stainless steel surgical tables and scalpels were on the right, while cabinets filled with medication were on the left.

Choi Hoeon reached out and removed the man’s gag. Whether he was a soldier assessing the situation or not, he didn’t shout or beg for his life. Being an A-rank tracker, he must have received some level of education.

“Who are… you?”

The tracker didn’t have information about Choi Hoeon, a Yeouido Shelter researcher.

“Your nose keeps bleeding.”

Choi Hoeon, tapping the man’s cheek as if feeling sorry, turned the faucet near the surgical table. As he pulled out the hose attached to the faucet, water flowed onto the floor. Holding the anxious man’s hair, Choi Hoeon lifted his head.

He inserted the hose into the bleeding man’s nose. The water that entered through the nose flowed out of his mouth. The man’s eyes became red and congested as he half-swallowed and half-spit out the continuously flowing water. Despite trying to pull his head away, he couldn’t move due to the immense force.

Choi Hoeon removed the hose from the man’s nose. Then, he used the water from the hose to clean the floor. While the man coughed, Choi Hoeon locked the faucet and returned to his seat.

He gently raised the satisfied face, wiping it with a soft touch of his palm.

“Was Second instructed to track Kwak Soohwan?”

“Cough, splutter.”

The man, spitting out water, couldn’t answer Choi Hoeon’s question. Choi Hoeon grabbed the man’s chin, laying his body flat on the surgical table. After pulling up the hanging belt to secure the body again, he put on latex gloves.

“What are you… trying to do.”

Pressing his palm against the man’s abdomen, he squeezed firmly, causing the man to vomit water again.

“No matter how warm it is in Busan, winter can be cold, right? There were a lot of rabbits in the mountains when I was young. If you remove all the rabbit blood and grab the ears to pull down, the intestines pop out through the anus. Then you can neatly brush off the rabbit fur. But I think it could work for humans too.”

When Choi Hoeon picked up the scalpel, the man hastily spoke up.

“Y-Yes, Second is correct.”

Choi Hoeon reached into the man’s shirt and removed his military ID.

“It’s true! I don’t know the reason. We just follow orders.”

He glanced at the insignia and name. Choi Hoeon turned on the water again and this time inserted it into the man’s mouth. Deep into the throat, he blocked the mouth with his hand. The man struggled, but Choi Hoeon sighed as if bored. As the chest and abdomen visibly swelled, he removed the hose.

“Well done. Our captain needs to recover.”

Choi Hoeon gently wiped the man’s forehead as he regurgitated water. The captain thought no matter what he said, this guy would kill him. Screaming hysterically without knowing where he was or who this man was. It was more terrifying that nobody would know of his death. Choi Hoeon patted the captain’s head once again.

“Did Second instruct to capture Kwak Soohwan only? Or kill? Or did he say to bring Dr. Seokhwa?”

The captain was confident that he had more information than expected. The superiors said that if necessary, it was okay to kill Kwak Soohwan, and they ordered to capture Seokhwa.

“B-Both. Both.”

“Locked up in this cold and narrow basement, the city won’t search for you, sir?”

Choi Hoeon looked genuinely pitiful and gloomy.

“That’s the policy. But that policy is terribly wrong. How can failing to protect my citizens and soldiers be a policy? If it were my people being held like this, I would do whatever it takes to find them.”

Coughing, the captain vomited federal water. Now he seemed to deduce Choi Hoeon’s identity.

“You bastard… You’re a rebel, aren’t you?”

Standing up, Choi Hoeon looked down at the captain expressionlessly.

“You got it wrong.”

He slowly sliced the captain’s chest with the scalpel. At the unbearable scream, he took off his gloves and shoved them into the captain’s mouth. Slamming the door shut, Choi Hoeon turned to the incoming person.

“I’m really disappointed, Mom.”

The woman hunched her shoulders.

“Kwak Soohwan has been obsessing over Dr. Seokhwa more than necessary.”

The woman tried to make excuses but then closed her mouth.

“How did Major Kwak Soohwan seem to you?”

“He didn’t seem relaxed enough to be persuaded. He tried to harm me without any hesitation. Although Dr. Seokhwa was controllable, Major Kwak Soohwan seemed relentless.”

The evolution Rainbow City aimed for was the emergence of a few mutants to protect the city, while Dr. Wonho’s goal was the complete evolution of humanity.

Kwak Soohwan was an embryo that escaped all the flaws of the newly born Choi Hoeon and Seokhwa. Dr. Wonho and Kwak Soohwan’s parents created genes close to perfection, and the mission of those genes was to achieve repeated evolution through reproduction. Wasn’t the present the best time for evolution?

The beginning of evolution was survival because survival leads to reproduction. Kwak Soohwan would inevitably cling to the instincts ingrained in him. And Seokhwa, who was free from Adam, had to take on the role of a kind of leader who could spread the ideology of evolution. Rainbow City had to collapse under the crowds dreaming of a new world.
